Product details
Overview
DG611DJ-E3 from Vishay Siliconix is a high-speed, low-glitch quad SPST analog switch IC designed for precision signal routing in fast-switching systems. It features 12 ns turn-on time, 18 Ω on-resistance, ±2 pC charge injection, 500 MHz bandwidth, and operates from ±5 V to ±10.5 V dual supplies or 5–21 V single supply. It is used in pixel-rate video switching and DAC deglitching where minimal transient error and wide analog bandwidth are critical.
For engineers reviewing the DG611DJ-E3 datasheet, DG611DJ-E3 pinout, DG611DJ-E3 application, or DG611DJ-E3 equivalent, key selection criteria include guaranteed 12 ns tON at 3 pF load, sub-2 pC charge injection for sample-and-hold accuracy, 74 dB off-isolation at 5 MHz, and compatibility with 5 V CMOS logic levels (VIH ≥ 4 V, VIL ≤ 1 V).
Technical Context
The DG611DJ-E3 implements four independent bidirectional SPST switches using Vishay's proprietary D/CMOS process-n-channel DMOS FETs for low RDS(on) and fast switching, paired with low-power CMOS control logic and level translators. Each channel conducts equally in both directions when on and blocks up to 16 Vp-p when off.
It employs an epitaxial layer to prevent latch-up and minimizes parasitic capacitances (CS(on) = 10 pF, CD(off) = 2 pF) to ensure clean, low-glitch switching. Logic inputs respond to standard 5 V CMOS thresholds (0 V–1 V low, 4 V–5 V high), with dedicated VL pin enabling flexible logic supply referencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| tON | 12 ns typical at RL = 300 Ω, CL = 3 pF - enables sub-20 ns aperture uncertainty in fast sample-and-hold circuits |
| RDS(on) | 18 Ω typical at V+ = 15 V, V− = −3 V - ensures low insertion loss and minimal signal attenuation in 50 Ω systems |
| Charge injection | ±2 pC maximum - limits step-induced offset errors in precision sampling applications |
| Bandwidth | 500 MHz - supports full-swing video and RF signal routing without high-frequency roll-off |
| OIRR | 74 dB at 5 MHz - provides strong isolation between active and inactive channels in multi-source systems |
| Analog range | V− to (V+ − 5 V) - allows rail-to-rail analog signal handling within safe operating voltage margins |
| Supply range | V+ = 5–21 V, V− = −10–0 V - supports unipolar (e.g., +15 V only) and bipolar (e.g., ±5 V) operation |
Pinout & Package
DG611DJ-E3 is housed in a 16-pin plastic DIP package (JEDEC MS-012), 10.0 mm × 4.0 mm body, 2.54 mm lead pitch, through-hole mountable. Pin 1 is top-left corner (notch side), with pins numbered counter-clockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control inputs | Active-high logic inputs controlling S1–S4 switches; VIH ≥ 4 V, VIL ≤ 1 V, compatible with 5 V CMOS |
| S1–S4 | Source terminals | Bidirectional analog source nodes; conduct equally in both directions when switch is ON |
| D1–D4 | Drain terminals | Bidirectional analog drain nodes; support analog signals up to 16 Vp-p when OFF |
| V+ | Positive supply | Primary positive rail (5–21 V); powers DMOS switches and internal level translators |
| V− | Negative supply | Negative rail (−10–0 V); required for bipolar operation and extended analog range |
| GND | Ground reference | Analog and digital ground return; must be low-impedance for low-noise switching |
| VL | Logic supply | Independent 4–V+ logic voltage reference; decouples logic threshold from analog supply rails |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Single-supply only (2.7–12 V), 15 Ω RDS(on), 15 ns tON, no V− pin - lacks bipolar operation capability | Not suitable for ±5 V or ±10 V analog signal routing; limited to unipolar industrial I/O | Select DG611DJ-E3 when bipolar supply and rail-to-rail analog range are required |
| ADG1419BRUZ | 44 V supply max, 1.3 Ω RDS(on), 22 ns tON, 0.25 pC charge injection - lower RDS(on) but higher cost and larger SOIC-16 package | Better for low-distortion audio or precision instrumentation; overqualified for video switching | Choose DG611DJ-E3 for cost-sensitive, high-speed video or DAC deglitching where 18 Ω RDS(on) is sufficient |
Compared with MAX4617ESE+ and ADG1419BRUZ, DG611DJ-E3 uniquely balances 12 ns speed, ±2 pC charge injection, and true dual-supply flexibility in a legacy-compatible DIP package-making it optimal for retrofitting high-speed analog routing in existing video, test, and communications hardware.

FAQ
What is the maximum analog signal voltage range supported by DG611DJ-E3?
DG611DJ-E3 supports an analog signal range from V− to (V+ − 5 V) under recommended operating conditions. With V+ = 15 V and V− = −3 V, this yields −3 V to +10 V (13 Vp-p). Absolute maximum ratings allow up to 16 Vp-p across S/D terminals when the switch is off, provided signals stay within (V− − 0.3 V) to (V+ + 0.3 V) to avoid diode clamping.
Does DG611DJ-E3 require a negative supply to operate?
DG611DJ-E3 supports both single-supply (e.g., V+ = 15 V, V− = GND) and dual-supply (e.g., V+ = +5 V, V− = −5 V) configurations. A negative supply is not mandatory but enables true bipolar analog signal handling (e.g., ±3 V signals) and extends the usable analog range beyond what unipolar operation allows.
How does the VL pin function in DG611DJ-E3?
The VL pin sets the logic threshold reference independently of V+ and V−. It must be biased between 4 V and V+, and determines VIH (≥ VL × 0.8) and VIL (≤ VL × 0.2). This decoupling allows reliable 5 V CMOS interfacing even when V+ is set to 12 V or 15 V, preventing logic misreads due to supply scaling.
Can DG611DJ-E3 be used in place of DG611DJ without modification?
Yes - DG611DJ-E3 is a RoHS-compliant, lead-free variant of DG611DJ with identical electrical specifications, pinout, and package dimensions. The "-E3" suffix denotes matte tin lead finish per JEDEC J-STD-609, and no PCB layout or schematic changes are needed for drop-in replacement in new designs or legacy rework.
What is the thermal derating behavior of DG611DJ-E3 above 75 °C?
DG611DJ-E3 (16-pin plastic DIP) has a power dissipation derating of 6 mW/°C above 75 °C. At 100 °C ambient, its maximum allowable power drops from 470 mW (at ≤75 °C) to 470 mW − (25 °C × 6 mW/°C) = 320 mW. This must be verified against actual channel current, RDS(on), and ambient conditions in thermally constrained enclosures.
